Description

Smart Card Capable of Controlling RF Function

The present invention relates to a smart card, and more particularly, to a smart card capable of improving the RF function to enable or disable the RF function in accordance with the user's selective use or not.

In general, smart cards have an IC chip equipped with a microprocessor, an operating system, a security module, and a memory to have a storage function, a calculation function, and a security function. Thus, a smart card has a larger storage capacity and a higher security than a conventional magnetic card. Therefore, it can be used for various purposes.

This smart card can be used for various purposes such as credit card, transportation card, ID card, etc. in addition to basic general banking business, and pays the usage fee such as congestion toll, parking lot, toll gate, etc. Not only can be used as a means of payment, it can also be used to purchase goods or pay content in an internet shopping mall.

The smart card can be classified into various types according to the classification criteria, but the IC chip is classified into a contact card, a contactless card, and a combination card according to the manner in which data is read from the card, and recorded on the IC chip of the card. Devices for reading the read data are classified into contact readers and contactless readers according to the dependency of the smart card.

On the other hand, smart cards such as the contactless card and the combination card, as shown in Figure 1, the antenna coil 31 in a loop form along the edge on one side of the antenna coil insertion layer 30, a part of the The antenna terminal 34 is connected to the antenna coil.

When the antenna terminal 34 is formed, the lower protective layer 10, the lower printed layer 20, the antenna coil insertion layer 30, the upper printed layer 40, and the upper protective layer 50 are sequentially stacked. After that, the card body 70 composed of one laminate is constituted.

Subsequently, a recess groove 72 is formed on one side of the card body 70 so that the antenna terminal 34 of the antenna coil 31 is exposed to the outside, and then the antenna terminal 34 exposed from the recess groove 72. ), The viscous conductive adhesive 18 is applied, and the COB module 1 including the IC chip is inserted into the recessed groove 72.

When the COB module 1 is inserted into the recessed groove 72, heat and pressure are applied on the COB module 1 to bond the treated hot-melt tape and the card body 70 to the bottom of the COB module 1. At the same time, by curing the conductive adhesive 18, the antenna terminal 34 of the antenna coil 31 and the terminal of the COB module 1 are connected so as to be electrically connected, thereby manufacturing one smart card.

Accordingly, when the smart card approaches the card reader, an induction electromotive force is generated in the antenna coil to activate the RF function of driving the IC chip of the COB module 1, so that the information stored therein is not directly contacted with the outside of the card reader. As it can be read, it is strong in the external environment, and it is easy to use and has excellent utility.

However, such a conventional smart card is an RF function is activated regardless of the card holder's willingness to use the card if only the minimum recognition distance to activate the COB module is secured, such as illegal copying, information leakage and illegal transactions. There is a security problem that can cause an accident, and if a plurality of smart cards in the wallet has a plurality of smart cards are activated at the same time the RF function error occurs, which makes the card unavailable and the card user in the wallet There was a problem in the use of having to withdraw only the smart card to be used separately.

Accordingly, the present invention is to solve the above problems, the purpose is to enable or disable the RF function of the antenna coil according to the card holder's willingness to use the card can increase the safety and convenience of use in security To provide a smart card that can control the RF function.
